No one know how to do this? If I copy fceux binary to /usr/bin (also it give me some errors about libs, then I copy them from ubuntu), it gives me an error from native webOS libstdc++ and libc. How can I fix these errors?

P.S. I need only free NES emulator. I can't buy from App Catalog. Also I have NES.emu sources, but no one helped me to compile them.
